BACKGROUND

Clips are used in non-residential building and construction to securelyconnect one metal framing component to either another metal framingcomponent or a structural building component.

U.S. Pat. No. 5,906,080 (the “080 patent”) discloses such a clip. Theapparatus [described in the '080 patent] is a bracket with a first platefor mounting to the primary structure and a second plate for mounting insliding relation to the wall studs. The second plate is formed withslots which are vertically oriented, a fastener with a spacer arefastened through each slot.

According to claim 1 of the '080 patent, the bracket disclosed thereinhas “ . . . a first plate having a linear edge; and a second platehaving a selected thickness and a second linear edge and beingintegrally connected to the said first plate with said first linear edgeand said second linear edge coinciding, said second plate formed with atleast one linear slot therethrough, said slot having a selected width.”

U.S. Pat. No. 8,181,419 (the “419 patent”) states that “[f]or a morecomplete and detailed description of such connection devices, referenceis made to U.S. Pat. Nos. 5,906,080; 6,612,087; 5,467,566; and7,503,150; . . . ”

The '419 patent goes on to state that “[t]he degree to which suchdevices function as intended is dependent upon proper installation. Forexample, should a shouldered screw be inserted and tightened off centerin the slot, the shoulder would overlap and clamp the plate to themember. This clamping would render the connection more or less rigid andnot slideable. Avoiding this kind of improper installation requires timeand installer dexterity to properly align the screw in the slot.”

While the two preceding references refer to clips where the member—e.g.strut—slides in the clip, there are also several types of fixed clips.There are over 20 different design iterations of clips with varyinglengths, widths, thicknesses, and hole patterns.

The prior art clips are typically transported to and within the job sitein 5 gallon plastic buckets. For example, if one needs seven (7)different types of clips for a job on the 5^(th) floor of a building,then one orders and hauls 7 separate 5 gallon buckets up the elevator orstairs to the 5^(th) floor, each bucket containing a different type ofclip.

There is therefore a need for an adjustable clip to replace the multiplenon-adjustable clips, and that will enable distributors to stock andinventory fewer types of clips, reduce warehousing complexity, and thusreduce their costs. The reduced number of clip designs will also allowcontractors and builders to reduce the complexity of clip management andhaulage at the job site. For instance, in the preceding example, onewould only need a single 5 gallon bucket containing a single type ofclip instead of the 7 different buckets each containing a different typeof clip.

The slide plate elongated hole(s) may allowslideable movement between the slide plate and the connector plate whenthe slide plate elongated holes are used to secure the connector plateto the slide plate by passing a fastener, such as a screw or bolt,through the slide plate elongated hole and a corresponding connectorplate hole.

FIG. 9A shows one embodiment of a method of assembling an adjustablerigid clip assembly. In this embodiment, the slide plate tabs (440) arepre-bent, while the connector plate slots (340) extend through thejuncture (500) and the anchor plate (200) has an anchor plate tab slot(240) with one side of the anchor plate tab slot having an anchor platetab slot width at least spanning the slide plate tab bent over width.

As shown in FIG. 9A, the slide plate tabs (440), which are pre-bent,pass through the anchor plate tab slots (240) and slide into theconnector plate slots (340). FIG. 9A also shows connector plate slotholes (380) in the connector plate located proximate to the connectorplate slots (340). These connector plate slot holes may be used to affixthe slide plate to the connector plate by passing a fastener, such as ascrew or bolt, through the slide plate tab notch (480) and the connectorplate slot holes. In some embodiments, the slide plate tabs which havebeen pre-bent may be bent further to a position where they engage a faceof the connector plate to hold the slide plate in place during or afterinstallation. In so doing, one-handed installation is facilitated aswell.

FIG. 9B shows a separate embodiment of a method of assembling anadjustable rigid clip assembly. In this embodiment, the slide plate tabs(440) are not pre-bent. The connector plate slots (340) extend throughthe juncture (500) and the anchor plate (200) has an anchor plate tabslot (240). However, in the embodiment in FIG. 9B, the anchor plate tabslot width is less than the slide plate tab bent over width.

As shown in FIG. 9B, the slide plate tabs (440) pass through the anchorplate tab slots (240) and slide into the connector plate slots (340).Optionally, after passing the slide plate tabs through the anchor platetab slots and into the connector plate slots, the slide plate tabs maybe bent over to form a slide plate tab bent over tab width which willnot allow the slide plate to slide back through the anchor plate tabslots without un-bending the slide plate tabs.

FIG. 9C shows a separate embodiment of a method of assembling anadjustable rigid clip assembly. In this embodiment, the slide plate tabs(440) are not pre-bent. Also in this embodiment, the connector plateslots (340) do not extend through the juncture (500), and the anchorplate (200) does not have anchor plate tab slots (240).

As shown in FIG. 9C, the slide plate tabs (440) pass through theconnector plate tab slots (340). Optionally, after passing the slideplate tabs through the connector plate tab slots (340), the slide platetabs may be bent over to form a slide plate tab bent over tab widthwhich will not allow the slide plate tabs to slide back through theconnector plate tab slots without un-bending the slide plate tabs.

FIG. 10A to FIG. 10C shows an embodiment of a method for assembling anadjustable rigid clip assembly comprising slide plate tabs (440) whichare not pre-bent, and then bending the slide plate tabs. First, theslide plate tabs, which are not pre-bent, pass through the connectorplate tab slots (340) as shown in FIG. 10A. Next, the operator begins tobend the slide plate tabs as shown in FIG. 10B. FIG. 10C shows the slideplate tabs fully bent over so that the slide plate tabs cannot slideback through the connector plate tab slots without un-bending the slideplate tabs. In some embodiments, the slide plate tabs may be bent to aposition where they engage a face of the connector plate to hold theslide plate in place during or after installation. In so doing,one-handed installation is facilitated as well.

As shown in FIG. 11, the juncture (500) is the intersection of theanchor plate (200) and the connector plate (300), and corresponds to thethickness of the anchor plate and connector plate.

It is not considered necessary that each combination of slide plate tabsand connector plate slots be of the same configuration. For example, insome embodiments, one slide plate tab may be pre-bent and thecorresponding connector plate slot may extend through the juncture withthe anchor plate having an anchor plate tab slot having an anchor platetab slot width corresponding to at least the width of the slide platetab bent over width as shown in FIG. 9A, while a second slide plate tabmay not be pre-bent as shown in FIG. 9B and the corresponding connectorplate slot may extend through the juncture with the anchor plate havingan anchor plate tab slot which may or may not have an anchor plate tabslot width corresponding to at least the width of the slide plate tabbent over width.

Bending the slide plate tabs (either pre-bending or post-bending) is notconsidered necessary. In some embodiments, one or more of the slideplate tab(s) will not be bent at all.

This assembly has been found to be very useful on construction jobsites. By replacing many different brackets with one bracket, the amountof inventory and space taken at the actual site of installation isreduced. Time hunting for the right bracket is also eliminated.
